Hello!
A couple grad. students at UMich, Ann Arbor have built a system for
electrophysiology, i.e. to record electrical activity from neurons, and
are showcasing it at the Society for Neuroscience conference. This type
of equipment usually costs $40,000, and they're doing it for $100!

* j/k. I'm not advocating animal abuse or amature surgeons.
